It's not overly complex in what it does, it's 3 registry edits and an additional manila file. I haven't delved into the manila file yet but seeing as how the registry edits disable the standard start menu and unhide the manila menu:
Code:
<characteristic type="Registry">
<characteristic type="HKCU\Software\HTC\Manila">
<parm name="EnableStartMenu" value="0" datatype="integer" />
<parm name="Manila://programs.page.hidden" value="0" datatype="integer" />
</characteristic>
<characteristic type="HKLM\Software\HTC\EnlargeMenu">
<parm name="EnableManilaStartMenu" value="0" datatype="integer" />
...It is a Mode9 manila file and I know less than nothing about modifying those but I do know that those are where the scripts live...It might end up being nothing more than the equivalent of a shortcut.
I'll install it in the morning (having trouble seeing straight after a LONG week today) and see if I can figure even a part of it out. After poking around with the M9 editor this one looks fairly straight forward so it might be a good one to learn on.
